The USB-IIRO4-2SM data-acquisition module contains four optically isolated digital inputs, four Form C electromechanical relay outputs, and two RS-232/422/485 serial communication ports, all packaged in a rugged, 4 × 4 ×1.8-in. industrial enclosure. The module features a custom, high-speed driver said to provide a maximum data throughput that is 50 to 100 times faster than a USB human-interface device (HID) driver. A DIN-rail-mounting option is available.
